Tolong bantu terimakasih

3 kuadrat + 4 kuadrat = 9+16 + 25 akar 2 = 5 ( sisimiring)
14+8+ 10 (sisi miring kali 2) 
keliling = 32

Keliling = Jumlah semua sisi

Gunakan rumus phytagoras!
Sisi Miring Trapesium = 3² + 4² = 9 + 16 = 25
                                   =√25 = 5 cm
Keliling Trapesium = 8 cm + 14 cm + 5 cm + 5 cm = 32 cm
